Yuko,
It may have worked in Version 4.2, but it is not a documented form of the
expression. The proper expression would be
Sum[1, {i,1000001}]
Sometimes undocumented features will work but you can't count on them in
future versions. I think that is what happened in this case.

Hello there,
Try the following simple expressions in Mathematica(ver5)
Sum[1, {1000001}]
Product[1, {1000001}]
There are no problems in ver 4.2.
